Ivan's coupe: bodywork is done

[Ivan141]

Small update (and a question for the walking 86 dictionairies among us).
I opened up the front chassis beam yesterday in order to weld a captive nut back in place (it had broken loose due to being towed regularly with slack on the bolt). I destroyed the bumper bolt in the process (the one that bolts up to the front, not the top-down one). I really need this bolt to be able to mount my car in a rotisserie, but it's some bloody impossible to find size, as toyota seems to prefer to use.

Does anyone know the exact size & thread by any chance? I can measure it up myself if it's a size that's in my tap&die kit, but I might as well ask first.
